Insp. Thomas: [to his squad] He may be abroad, traveling on a false passport. What you're going to do now is to go down to the Passport Office. Get a complete list of every passport application for the last three months.
Special Branch Detective: But, sir...
Insp. Thomas: I don't care who's closed, wake the buggers up! Then take all those papers down to Somerset House, get started on checking the applicants' names against death certificates. Not birth certificates, mind you. If you find a passport filed by someone who died as a child, the one who filed it might be our man. If you don't find anything in the first three months, go back another three, and another three if you have to. Right, off you go!
